I think that like Linux it is not a tunable setting. The OS will us
as much memory as it can while still meeting the memory resource needs
of the applications running on the machine. The upshot is -- buy more
memory. The take-away from the above doc quote is to drop the amount
of shared_buffers for PostgreSQL, since you can control that.
